* more build dependencies
* fix for cmake < 3.11
It cannot do ADD_LIBRARY(... ALIAS ...) on IMPORTED targets
* another fix for cmake 3.10.2
It doesn't know about CMAKE_CXX_STANDARD=20,
let's add the correct flag manually
* gcc 8 on aarch64
utils/common/simd_arm.h:241:16: error: need ‘typename’ before ‘simd::TypeToVecWrapperType<T>::WrapperType’ because ‘simd::TypeToVecWrapperType<T>’ is a dependent scope
* Adds CompressInterfaceLZ4 which uses LZ4 API for compress/uncompress.
* Adds CMake machinery to search LZ4 on running host.
* All methods which use static data and do not modify any internal data - become `static`,
so we can use them without creation of the specific object. This is possible, because
the header specification has not been modified. We still use 2 sections in header, first
one with file meta data, the second one with pointers for compressed chunks.
* Methods `compress`, `uncompress`, `maxCompressedSize`, `getUncompressedSize` - become
pure virtual, so we can override them for the other compression algos.
* Adds method `getChunkMagicNumber`, so we can verify chunk magic number
for each compression algo.
* Renames "s/IDBCompressInterface/CompressInterface/g" according to requirement.
This patch:
1. Removes the option to declare uncompressed columns (set columnstore_compression_type = 0).
2. Ignores [COMMENT '[compression=0] option at table or column level (no error messages, just disregard).
3. Removes the option to set more than 2 extents per file (ExtentsPreSegmentFile).
4. Updates rebuildEM tool to support up to 10 dictionary extent per dictionary segment file.
5. Adds check for `DBRootStorageType` for rebuildEM tool.
6. Renamed rebuildEM to mcsRebuildEM.
* This patch adds rebuildEM tool support to work with compressed files.
* This patch increases a version of the file header.
Note: Default version of the `rebuildEM` tool was using very old API,
those functions are not present currently. So `rebuildEM` will not work with
files created without compression, because we cannot deduce some info which are
needed to create column extent.
Remove generated Makefiles
Update Makefile.am to specify RPATH as a subdirectory of --prefix
Remove configure artifacts such as config.log, config.h, etc
Remove unneeded backup files (files ending in tilde ~)
